So, I just got done chatting with AT&T customer service, via online chat, and I was asking questions about the phone constantly switching between HSDPA, and UMTS. I asked if this was normal, and she said mentioned that it is as they are upgrading the networks. She asked me for my zip, and did a check and said that they are currently working on upgrading in the area (Manhattan). She also did say that this phone will be able to connect to the LTE network when that is rolled out later this year (though from the sounds of it on this forum, that is highly unlikely).
Then, I asked about the SIM card. I mentioned I came from the Samsung Captivate, and that my SIM card says 3G on it. I said is this affecting my phone and contributing to my phone spending more time on UMTS than HSDPA? And her response was...
"Yes, you will need a new SIM card. If you can give me your address, I will be able to find a location in your area that can give you one free of charge."
I'm going into the store tomorrow to pick one up. Hell, why not?! Free and new is always good. Doubt it is the SIM, though it could help in the long run.
Thoughts?
AT&T needs to train their CSR staff. This phone won't do LTE and the 4g card won't make any difference.

It is true you will need a 4g sim card to get LTE. The Inspire is only hsdpa+ 3.5G lol

3.5g is Hspa
hspa+ is 3.75
Well, I had the "captivate->inspire no mobile data" thing happen a couple of days ago, went to the store, dude did some stuff on the computer, didn't work, and the only thing left to do was to change the SIM card (from 3g to the new one), which worked.
So the moral of the story is you're better off having them give you a new sim, even if the old one still looks like it's working, even partially, as was the case for me.

This is all good info. Thanks all for sharing. I'd be curious to hear others experiences after using a newer SIM card.
When I got the phone a day early, the guy had problems registering the new sim so I'm just using my old 3G card. Runs fine, maybe slower without the build.prop edit but it doesn't matter much where I live. Do what works for you.

I just recently switched from a captivate to inspire at an ATT store. The salesman put in a new sim card in the inspire instead of putting my captivate sim card in. When I asked why, whether this is true or not and I question too, he told me that in order to get 4g connection, I need a new sim. He deactivated my old sim and told me to shred it. When I got home, I placed my old sim back in and sure enough it was deactivated. I then placed my new "4g sim in my captivate and it worked. " I would like to know if a deactivated sim can be reactivated before I dispose if it.

He was wrong about "needing a 4G SIM", but you can't reactivate a deprovisioned SIM.
Gotcha. That sux. I also asked the salesman if the inspire would connect to the LTE network when it rolls out and he said yes. Imo, if ATT current lineup of 4g phones won't connect to LTE, that is a class action lawsuit waiting to happen. ATT can't afford anymore negative publicity of these proportions. We can speculate, but in the end, we won't actually know until LTE goes live.

From what I've read the networks are backward compatible to provide a seamless transition between networks, but a special chipset is still needed to connect to LTE, which as far as I know the Inspire doesn't have

well we know for a fact the inspire does not have an LTE radio, so that issue is for sure a "no". i really dont see much to back up a lawsuit though...
I think the key to your response is the statement "no current AT&T phones will ever be able to connect to the LTE network". I believe this was carefully and specifically worded, which leaves the techs in the store correct but misrepresenting what will happen. The phones will connect to the LTE towers because they will be the same towers as the 3G towers, but they will only connect as 3G devices with HSPA+ which means they could be capable of 4G speeds on these upgraded towers. It is true that they will not connect to the LTE network itself which I don't believe is really saying much. I doubt ATT is running multiple separate receivers on each tower for all their different network types. I would have to believe they are buying equipment that is capable of supporting their legacy phones while bringing new features in.
It still comes down to the same thing, if you were expecting an LTE feature on this phone in the future, you bought the wrong device. There is a reason the Thunderbolt is more expensive than the Evo and Inspire, it has an LTE chipset in it. Beyond that fact there really isn't a major difference between this phone and the Thunderbolt.
Just walked out of the store with a new "4G" SIM card. Yeah, from the sounds of it, especially after reading the comments here, all this SIM card is, is a re-branded one of the 3G card.
The only people that have told me this phone will not be able to access the LTE network are here on the forum. Thus, I trust this forum and the people here far more than any person at AT&T. Nevertheless, they absolutely need to differentiate between LTE and HSPA+. This is a fact: Every single person I have spoken to at a AT&T store in Manhattan, including the regional manager (whom set me up with this phone, for free, after my complaint about my previous phone to the CEO of AT&T wireless) has mentioned and specifically stated this phone will be able to access the LTE network.
It does not bother me one bit that I will in fact not be able to access the LTE network with this phone. No. I'm perfectly happy with the speeds now, and that I can access HSPA fine here in the city (when I am connected to HSPA, that is). In any case, by the time LTE is accessible to the masses, we'll be able to upgrade our phones. It will be quite sometime before most folks will ever be downloading with the speeds of LTE.
The real issue at hand now is being able to get the full upload/download speeds of HSPA as it still seems to be capped! One step at a time I guess. HSPA is available, I can access it fully throughout the city, however my upload speeds are still capped. This is the first hurdle to clear before going on to the next - LTE.

I dropped by a local AT&T store to check out the Inspire and the sales rep mentioned that if I upgraded from my HTC Tilt 2, I needed to get a new SIM with a 4g data plan. He said that my existing SIM would not have access to any data in the Inspire. I doubt the SIM cards themselves are really different. They are just probably entered into the AT&T database under different data plans.
So if I do that, can I put the new 4g SIM back into my older HTC Tilt 2 and still get data?
I have to support many different phones and I need to be able to move my SIM around.
Man do they TRAIN these reps at all?
The 4G sim is for LTE. I have a 3G sim and my data works just fine.
The 4G sim is supposed to be backward compatible.
3g here working fine

i've got an old 3g sim and i've been connected to h+ with dl speeds upwards of 3.5 mb/s.
as stated, the 4g sim is for lte, not hspa+...the inspire doesn't even accept lte 4g.
The sales rep even showed my a memo in a book that stated the 3g SIM would not allow access to ANY data in the Inspire.
So it wasn't the sales rep's fault, he was given bad information.

Gotcha. My sales guys said he was headed to a training on the new 4G phones this weekend. I knew more than he did
My rep never even mentioned having to change my data plan if I upgraded to 4G. He did, however, mention that they did need to train the reps on the phones that are released...it took him a few minutes to remove the battery door (I was so hoping he wouldn't scratch up the phone before I got to use it - but, he didn't), and I even had to tell him where the SIM and SD cards went (he was looking for it in the battery area, but I noticed there was a door at the bottom that might come off - BINGO!).
AT&T really does need to provide more training for the CS reps. I'm glad I didn't have to change anything; even found a feature I wasn't using that saved me $10 when he removed it (from when I was with Cingular). I also asked about state employee discounts, and am now getting a 15% discount off my monthly bill. SWEEEEEEEEEEET!
I just took the 3G SIM out of my Nexus One... handed it to the AT&T sales rep...and kept my unlimited data plan.
I get H+ and I get very good speeds with no issue at all. Hmm..
The training is there, but it's up to the reps to take it seriously. They had trainings before release on each new phone and detailed instructions to reference. Unfortunately, many just click through the training and ignore the instructions. Btw, every rep was trained regarding the differences between hpsa+ plans vs previous data plans as well as differences between sim cards.
I have the inspire and was having some issues with dropped calls and dropped data. When i talked to the store reps they didnt know anything (go figure) when i called the corporate tech guys they told me to look at my sim card. If there is a 25 in the serial number then i have the right sim card for the phone, that it is the one that will connect to 4g when it comes. I looked at the sim card i was using when i was having the problems and it didnt have the 25 in the numbers, but since i got a new one that does i havent had any issues.
This was a great question. I had had the captivate and while rooted was getting the h in my signal area, and when I upgrades to the inspiewss VERY. Shocked I didn't need a new sim. I remember when the 3g ones came out and what a big deal that was.. all very interesting
Specs say there no LTE chipset in the inspire 4G like the thunderbolt

I moved from a 3Gs to my Inspire and didn't get a new sim. Just popped the one I had into my Inspire and told me I was good to go. I didn't have to get rid of unlimited data or anything.
haven't had issues with the sim card im my inspire....i've been using it for 3.5 years now.
Your "4G" sim will work in the Tilt 2 as a back-up. I did your exact upgrade (Tilt2-Inspire), and have popped the "4G" sim into my Tilt 2 to do a couple things on the network and it's worked just fine. My old 3G sim card was de-activated when I activated my "4G" so I can't speak to the Inspire working with a 3G sim. Might get better data speed till AT&T's real 4G comes online if it works though.
Like some of the others I was a little worried about losing unlimited when the CSR (did my upgrade over the phone) started talking about a new data plan, but at least this time they aren't stealing unlimited away from their customers.
I just upgraded to my inspire a week or so ago, and I have the same sim that was in my Iphone 3g. I do notice that me data connection is not stable, the speed fluctuates anywhere from .4 mbps to 6.5 mbps. Would the 4g sim cure this?

I know my way around around and all but I need to ask a few questions about 4g.
right now I have a vibrant with a $60 T-Mobile unlimited plan ( includes data/ no contract).
I plan on getting a g2x(not from T-Mobile) . would I have to get a 4g plan? or I can use my current one with 3g only? is 4g free as long as the phone is capable? and do I need a different sim card for the g2x?
lol sorry for bombarding u all with these questions.....thanks in advance.

yes is the $60 prepaid/ monthly plan but idk if its 4g....right now I get 3g (H) with 5gb cap then its slowed to 2g speed.
my main issue is I do no want to change the plan.....just phone
I may be misinformed but when I went from a Blackberry to the G2x, TMobile told me I would have to change the sim card to a 4g sim. Just throwing that out there.
I through my old sim card that was in my old Mytouch 3g slide into the G2x when i got it. Same plan nothing changed, just new phone. There really isnt a "4g" plan. And T-mobile's 4g network is technically 3g, they just call it that for whatever reason.
Sent from my LG-P999 using xda premium
They are all technically 3g. True 4g is around 100+ Mbps.
I think its just a selling technique. I had an old sim cards from years ago and transferred it into my g2x and ive had no issues at all. I did end up getting a new sim card anyway but the speeds remained the same. Also, it is unecessary to get a "4g" plan. I was talked into getting it when I upgraded the phone but then realized I could have just stuck to my old cheaper plan and the speeds wouldnt have changed. I talked to retentions at Tmobile and the lady even told me she has no idea why i was told to upgrade and she switched me back.
thanks everybody.....i am only limited to 5 thanks a day lol.

Well 4g stands for fourth generation. Which is a new technology or method. What Tmobile uses is improved hspa that's why its called fake 4g. Nothing new just really fast 3g. speed doesn't matter nor count has to be a new method of cellular transmittion.

Representatives aren't necessarily knowledgeable on this subject. However, the '4G SIMs' they often refer to are usually UICC/GBA/IMS SIMs. The difference between these SIMs and the old LEGACY SIMs (as they are labeled on the T-Mobile system) is that the legacy SIMs have a lifetime of around 90,000 authentications. Once these authentications run out, the SIM will no longer register on the network.
These authentications are pretty much each time you connect or hand off to a new data tower. On HSPA and HSPA+, these handoffs are occurring far more often than they did on EDGE or GPRS. In essence, with a legacy SIM you are running on borrowed time before your SIM simply begins to refuse to connect to the network. It sounds like a lot of authentications, but they run out astoundingly fast and some people have actually hit the SIM exhaustion point. This won't cause slow data speeds or inability to connect to data but still being able to use voice. Your phone will not authenticate on the network at all.
Any data plan will give you '4G', or rather HSPA+ as long as your phone has the appropriate modem and you are within the area covered by HSPA+ towers. You do not have to change data plans if you already have one. You also do not need a new plan for a new SIM card. If you have a legacy SIM card T-Mobile should replace it free of charge, unless that policy has changed. They are trying to be proactive in preventing customers from not reaching the authentication limit of the legacy SIM cards.
Your SIM card has absolutely nothing to do with your data speed, however on certain phones some features are tied to certain types of SIM cards, especially new IMS featured phones.

No carrier in the US at this time uses anything approaching the original 4G specifications, nor will be capable of doing so for years to come. Current LTE, HSPA+, and WiMax networks are stopgaps and were marketed by carriers as 4G despite them not being so, as they needed a way to market faster phones and networks to customers in a way that customers would understand. The specifications board that handles the generational specifications decided to submit to the desires of carriers and lower the boundaries for '4G'. HSPA+ was the quickest, easiest, least battery intensive, most reliable and most cost effective of the three to implement; which is why both T-Mobile and AT&T have been rolling these upgrades out to towers for some time.
This Q&A has more to do with the carriers as opposed to the phone. I was with sprint for atleast 8-9 yrs. They recently cancelled my account because of excessive roaming data usage i believe. I miss sprint (unlimited data plans), anyway. I just got the HTC One x and its a great phone, but its not like my previous Evo. Some of the settings I've come to use are gone. Like, does it suppose to be an option to turn the 4g signal off like on the evo or is it just "always on". I dont see any settings for that. Regardless its not an issue since the battery like on the HOX last longer than my evo, but I was just wondering
Another question concerning roaming. Does AT&T allow roaming(stupid question)? My parents stay in the boondocks, and when I visit them, there are times when my phone completely says "No service" I've never seen this before with sprint because the phone would just connect to the Verizon tower(s) nearby. Does at&t allow this? I read in the contract about excessive roaming..but I get great service at my house, just none at theirs. (sprint on the other hand roamed at both places. hence the termination)
Just a couple of carrier related questions i guess because I've only used sprint for the entire span of my cellphone usage, and this is my first time going with a different carrier.
You can't turn LTE off as far as I know, but I think you can turn "4G" somewhere in the setting which will put you on Edge though. Only roaming you need to worry about is if you're leaving the country.
Same as above, you wont be charged for roaming unless going outside of the US. But at&t phones don't roam internationally unless you enable them to through settings, also at&t is a little bit forgiving with roaming I was in US soil in a place with good signal, but my phone decided it wanted to roam an Canada 3g since the area I was in didn't have 3g I ran up $700 bucks in data, it was like two Facebook statuses, lol. But they refunded me since I had agreed to an international data block.
Sent from my HTC One X using xda premium
I too just switched from Sprint and an Evo to AT&T and a HOX. My experience has been different, though. I have family in the sticks and Sprint would always cut out. With AT&T I get consistent coverage and with HSPA+ I am getting data speeds 5x what I got before.
But I too wish I could turn off LTE since there's none here. When the kernel source is released this should become available though on custom roms.
ok i understand now about the 4g..but if at&t allows roaming, why did my phone show "no service" is there an option i need to untick/tick to enable it. Im pretty sure i clicked "data roaming" under network settings.
When I was on the Nitro, *#*#4636#*#* gets you to where you can click "Phone Information" and towards the bottom you can change the network type. From what I remember it does not persist past reboots.
However, when I try it on the AT&T HOX, I can't get the setting to stick, it just immediately switches back to LTE, so there may not be a way for us to set the phone to HSPA+...

Hey,
First of all let me say I know there are other posts concerning HTC Thunderbolt on AT&T, but mine is a little different.
My wife has an HTC Thunderbolt, loves it and wants to keep it. But we have moved to a new place a few months ago, and since then we don't get any verizon reception in our place! But AT&T works, and has data!
I have a Galaxy S, and will switch it soon to take another phone with another carrier. My wife has the HTC Thunderbolt, and doesn't want to switch phone and pay a new device.
Now one small detail about my wife, she is mainly interested in data only. If there is a way for her to get internet only on her phone, she would be happy. (She sends texts via Google Voice, and can place calls on her PC).
Do you guys know if it is possible to somehow get a tablet SIM card from AT&T, put the SIM card in the SIM card slot of HTC Thunderbolt, and get internet only on the Thunderbolt ? I know the phone is CDMA, but she doesn't really need the phone or text message capability. She basically just wants a small tablet. I'm mostly saying that because I know AT&T is LTE also, and that it might work ?
Otherwise did someone succeed into changing careers with something else ? Virgin Mobile ? Cricket ? etc...
Thank you
The tbolt is CDMA but has a sim slot?

tbolt does have a sim slot. It is a hybrid phone like all 4G Verizon phones. Basically the phone uses CDMA for 3G and phone. And uses the Sim card for LTE.
We could just buy a hotspot yes, but that's an extra device to carry which she doesn't want to do.
AT&T and Verizon use different LTE bands I believe...though they are both in the 700 mhz range I doubt the thunderbolt has the radio bits to get on AT&T bands, as it predates the existence of AT&T's LTE and I don't think hardly any devices even now have that capability. I can't see the harm in throwing in a sim to see what happens, of course.
The thunderbolt lte radio doesn't operate at the same frequencies necessary to work on at&t. It was made that way so that you can't switch the phone to other providers. It will work on other cdma type networks but GSM providers like at&t are a no go.
Sent from my Thunderbolt using Tapatalk 2
I'd like to add that the Verizon SIM is not your ordinary typical SIM. It's a RUIM card. I believe the thunderbolt can only accept these kind of cards as well. But in either case, Verizon’s LTE network operates in the upper half of the 700 Mhz range (746-787 Mhz), while AT&T’s operates on the lower half (704-746).

I don't see why not. Its not like you're moving from an old blackberry to an android. This would then complicate things because blackberry plans are specialized in how they use blackberry servers to retrieve email by text (thus the instantaneous notification without the battery drain). But I digress.
Simple answer yes, with no "hidden fees" lol
I agree. I don't thnk AT&T cares what specific device you have. Just regular phone, smartphone or blackberry. I've swapped my SIM card between devices before and it was fine. Hopefully you'll have the same experience.
ok so i can swap sim+ plans to i777/ my mom has iphone 3gs under contract still october 2011, if i put my plans in i777 can my mom put her sim card and plans into my skyrocket with no hidden fees/pay to use crap? Also, BONUS QUESTION which one is better for gaming i777 or ipod touch 5g?

You mentioned an unlocked phone, but from which carrier? It is a good rule of thumb that, if it's not an AT&T phone, it might not be capable of receiving all of the AT&T frequencies. (LTE, 4g, 3g ....).
A current sim card will allow a phone acess to AT&T's network. Sims are swappable, the phone you are using will be bound to the bands (frequencies) the internal radio is programmed to use. I suggest, a person wanting to use an unlocked phone, in any carriers network to first research (Google) the phone specs, and your network, to see if they are compatible. Their are several carriers that share the same bandwidth, but some only share some bands. Like AT&T shares some bands with T-Mobile but not all (LTE).
I hope this helps anybody with the decision on which phone it's capable of working on any given network.
